Patented Aug. 6, 1918.

Application filed October 25, 1916. Serial No. 127,540.

To all whom it may concern:

Be it known that I, HARRY ADAMS, a citizen of the United States, of theUnited States Navy, have invented certain new and useful Improvements inPhonographs, of which thefollowing is a specification.

My invention relates to a toy phonograph or sound producing device andthe object of my invention is to produce a toy phonograph which is novelin construction and operation, simple to operate and portable and alsolightwin Weight so that a child can readily handle and operate thedevice, and a further object of my invention istO produce a toyphonograph which can be manufactured at a very small cost.

Referring to the drawings in which like reference characters refer tolike part Figure l is a side elevation of the p 1on0- graph;

Fig. 2 is a front elevation of Fig. 1;

Fig. 3 is a detached View of the spindle upon which the record cylinderis mounted;

Fig 4 is a sectional view of the record cylinder; and Fig. is asectional view showing mechanism for increasing the speed of the recordcylinder.

In the accompanying drawings 1 represents the body portion or frame,which may be made of stamped metal having sufficient rigidity to form abearing for handles 2 and 3 located at either end of the frame 1. Thehandles 2 and 3 are located upon opposite sides of the frame 1 and aremounted at right-angles with the frame. Both of the handles are free toturn in the frame. The handle 2 being loosely mounted on the rod 4secured in the frame. The handle 3, is formed integral with a shank orspindle 6, which is provided with a screw thread, forming a means fordetachably securing the sound record cylinder 8 upon the spindle 6, topermit the records to be readily changed.

The sound record cylinder 8 consists of a cylindrical drum open at oneend to form a sound box to amplify the sound. A threaded sleeve 9 isformed centrally upon the record cylinder. Said sleeve 9 is adapted tobe screwed upon the spindle 6 of the handle 3, so that the recordcylinder 8 will rotate with the spindle 6. Upon the outer cylindricalsurface of the record cylinder 8 is impressed the record which is to bereproduced by the phonograph.

The record cylinder 8 may be formed of thin metal or any other suitablematerial but I, prefer to make it of papier mach. The record may beimpressed. directly into the material forming the record cylinder or therecord may be formedmpon some other material placed upon thecylinder, asshown in Fig.4.

A diaphragm 12 carrying astylus l3vis securely held .in a rigid rim 14;which iScarrind by an arm 15 pivotally mounted upon the pivot pin 16secured in the plated? which is pivoted upon a pin 18 secured in abearing 19 formed 11po11..t11 e. frame A spring 20 is secured at oneend. thereof by a rivet 22 and the opposite end of the spring isattached to. the arm 23 forming part ofthe hinged plate 17. The spring20 tends to hold the stylus 13 against therecord cylinden and thepivotpin 16 forms a hinge which permits the diaphragm to have a lateralmovement which allows the stylus 13 to follow the spiral groove upon therecord cylinder 8.

The diaphragm frame 14 is provided with a small finger grip 21 by whichthe diaphragm frame and the hinged plate 17 may be swung upon the pivotpin 18 and the diaphragm moved away from the record cylinder 8, for thepurpose of changing the record cylinders.

It will be seen that by holding the handle 3 securely in one hand androtating the other end of the frame around the handle 3, as a. center,that the diaphragm will be moved around the record cylinder and thestylus will be moved over the record groove formed in the recordcylinder and produce the sound.

The speed of the rotation of the record cylinder 8, in relation to therotary movement given to the handles may be increased by attaching tothe handle 30 a gear Wheel 31, as shown in Fig. 5. The handle 30 isloosely mounted in the frame 1, and the gear wheel 31 meshes with a gearwheel 32, of smaller diameter, secured upon the shaft 33 upon which thethreaded spindle is mounted for receiving the record cylinder. Byholding the handle 30 rigid and rotating the frame around the handle thelarger gear wheel will rotate the smaller gear Wheel at a faster speedand cause the record cylinder to rotate more rapidly.

Having thus described my invention I claim and desire to secure byLetters Patmet:-

1. In a device of the character described, the combination of a portableframe, a

sound record rotatably mounted in the frame, a diaphragm, a plate towhich the diaphragm is pivotally mounted, a pivot pin upon the frameupon which the said plate is pivotally mounted, a spring engaging theplate and tending to hold the diaphragm adjacent to the record and meansfor operatively moving said parts in relation to each other.

2. In a device of the character described, the combination of a frame, ahandle located at each end of the frame said handles disposed inopposite directions and at right angles with length of the frame, asound record connected with one of said handles and a diaphragm upon theframe.

3. In a device of the character described, the combination of a frame, ahandle located at each end of the frame, said handles rotatably mountedin the frame, a spindle integral with one of said handles, a soundrec-0rd secured upon said spindle and a diaphragm upon the frame.

4. In a device of the character described, the combination of a framehandles located at the ends of the frame, a sound record secured uponone of said handles, a diaphragm plvotally mounted upon said frame at apolnt between the two handles and a stylus upon said diaphragm forengaging a the sound record.

In a device of the character described, the combination of a frame,handles located. at the ends of the fran'ie, a sound record mounted uponone of said handles, a dia- :w"

phragm mounted upon the frame, a stylus on the diaphragm held inengagement with the sound record, and the hole structure so arrangedthat when the handle carrying the sound record is held in one hand andthe 4 HARRY ADAMS.
